Why is this so true?

I've noticed in my own life and the lives of others around me that those who have experienced deep sadness often develop a unique compassion for others. This quote really hits home: "I think the saddest people always try their hardest to make people happy because they know what it's like to feel absolutely worthless and they don't want anyone else to feel like that." From personal experience, when I've felt down or undervalued, I realized that small acts of kindness from others had a powerful impact on my mood and self-worth. Inspired by this, I found myself going out of my way to uplift those around me, hoping to spare them from feeling as isolated as I had. This cycle of empathy and care is stronger than it might seem—it’s a beautiful, though sometimes exhausting, way that sadness translates into genuine kindness. The emotional insight saddest people have helps them connect deeply and foster happiness in others, even if they continue to struggle privately. It's a reminder to cherish such individuals and recognize their strength and selflessness.
